CIRP’s main activities within High Speed Machining (HSM), or High Speed Cutting (HPC) and High Performance Cutting (HPC) topics within the STC “C,” are shown in Fig. 1. During the 61st General Assembly, 2011, in Budapest, a keynote paper on velocity in forming and cutting was presented and discussed including HSM and HPC (Neugebauer et al. 2011).

Introduction
The main challenges in metal cutting today lie in the development and application of innovative strategies aimed, firstly, at reducing cycle time and costs for better productivity and higher profitability, and also for improved performance and especially at reducing the amount of energy and resources used as well as emissions. In machining, for example, lightweight materials or high temperature alloys, the use of high machining conditions (HSM & HPC) is often restricted by the machine’s capacity or in terms of tool wear and workpiece machinability. In general, the use of high velocity may lead to reductions in cutting forces, power, and energy, something which will in turn have a positive effect on tool and machine design.
CIRP’s main activities within High Speed Machining (HSM), or High Speed Cutting (HPC) and High Performance Cutting (HPC) topics within the STC “C,” are shown in Fig. 1 (See “Definition”). During the 61st General Assembly, 2011, in Budapest, a keynote paper on velocity in forming and cutting was presented and discussed including HSM and HPC (Neugebauer et al. 2011). In the mid-1980s, Prof. Schulz initiated the HSM (or HSC) activities which are going on even today. Many CIRP meetings and conferences took place and a large number of scientific and technological papers were presented. During the 1990s, additional and new highlights such as dry cutting or MQL as well as hard cutting (HC) were emphasized.
